Generate GS1-128 Barcode in Crystal Report

1. In the demo file, there are a "BarcodeDemoData.mdb" that including "ID", "CustomerId", and "CustomerName", a "CustomerDataSet.xsd" to define the three columns and an extra column named "Barcode";
2. Open your Visual Studio; create a new .NET project with "Crystal Reports Application" as template;
3. Create a new report with Crystal Report. In the "Data" form, expand "Create New Connection", double click "ADO.NET (XML)" and select "File Path" as "C:\Demo\CustomerDataSet.xsd" in your downloaded sample dataset package;
4. You are back at the "Data" form. Double click "table", then click "Next". In the "Fields" form, double click or drag and drop "ID", "CustomerID", "CustomerName" to "Fields to Display" and click "Finish";
5. In "CrystalReport1.rpt", drag and drop the "Barcode" in the "Field Explorer" to report Section 3. And add "Avapose.linearbarcode.winforms.dll" to your project reference in "Solution Explorer";
6. Open your "Form1.cs", copy the following samples accordingly and debug.

private void Form1_Load(object sender, EventArgs e)
{
OleDbConnection aConnection = new OleDbConnection(
"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:/Demo/BarcodeDemoData.mdb");
aConnection.Open();
OleDbDataAdapter dataAdapter = new OleDbDataAdapter("select * from Customer"
, aConnection);
DataSet ds = new DataSet();
dataAdapter.Fill(ds);
//add a new column named "Barcode" to the DataSet, the new column data type is 
byte[]
ds.Tables[0].Columns.Add(new DataColumn("Barcode", typeof(byte[])));
Linear Barcode = new Linear ();
Barcode. LinearBarcode = Linear Barcode. Ean128;
foreach (DataRow dr in ds.Tables[0].Rows)
{
Barcode.BarcodeData = (int)dr["CustomerId"] + "";
byte[] imageData = Barcode.drawBarcodeAsBytes();
dr["Barcode"] = imageData;
}
CrystalReport1 rpt = new CrystalReport1();
rpt.SetDataSource(ds);
this.crystalReportViewer1.ReportSource = rpt;
aConnection.Close();

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) 
Handles MyBase.Load

Dim aConnection As New OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data 
Source=C:/Demo/BarcodeDemoData.mdb")

Dim dataAdapter As New OleDbDataAdapter("select * from Customer", aConnection)
Dim ds As New DataSet()
dataAdapter.Fill(ds)
'add a new column named "Barcode" to the DataSet, the new column data type is 
byte[]
ds.Tables(0).Columns.Add(New DataColumn("Barcode", GetType(Byte())))
Dim Barcode As new Linear()
Barcode. LinearBarcode = Linear Barcode. Ean128
For Each dr As DataRow In ds.Tables(0).Rows
Barcode.BarcodeData = CInt(dr("CustomerId")) & ""
Dim imageData As Byte() = Barcode.drawBarcodeAsBytes()

Next
Dim rpt As New CrystalReport1()
